As Tom said, you need to run me (yes, I'm Dino) in your newly built stroker for the break-in so that the rings, bearings, and other wear surfaces are properly bedded in. I ran dino in mine for the first 3000 miles and then switched to Mobil 1 0W-40. Did my first oil change at 600 miles and the second at 3000. Now I'm at 7300 miles and will do the third oil change at 9000 (synth. is good for 6000 miles).
